As credit has tightened, a company’s need
to generate cash has never been greater.
However, because customers and suppliers
are in the same position, the traditional
approach of ‘pay late and get paid early’
doesn’t work.
Companies have therefore looked at other approaches including
reductions in material inventories.
The problem is how to achieve this without disrupting production.
To meet production needs, a company needs sufficient material to
meet its usage and at the same time to provide a buffer against
variations caused by sudden changes in supply or demand.
In reality, because of poor analysis or a lack of trust in supplier
performance, companies also carry further inventory on a
just-in-case basis.
The process...
By working closely with customers, we have been able to develop some
advanced tools which simplify analysis. We use these to devise novel supply
arrangements, which result in significant inventory reductions combined
with high standards of on-time delivery performance.

The manufacturer enters parts requirements
into joint EDI system.
At ThyssenKrupp Aerospace operators prepare
parts in accordance with the agreed service level
agreement.
Material is packaged to protect components.
Material is delivered to the manufacturer’s
point of use.
Full online visibility of parts inventory and
min/max levels.
The case study
This approach was taken with a leading global
aerospace manufacturer:
The ThyssenKrupp Aerospace planning team
reviewed the customer’s demand forecast for
cut to size tube and bar and following an
electronic upload was able to use its planning
software to compare the future with its historical
usage.
This enabled forecast accuracy and other
variables such as mill lead times to be
established and an initial forecast by part
number was produced.
It was agreed that the customer’s inventory
should be reduced to one week. To support the
change, ThyssenKrupp Aerospace agreed to
carry a buffer to instil confidence and bought
back the customer’s excess inventory.
Within 6 months of the change this buffer was
reduced and the increase in confidence
encouraged the customer to outsource the first
stage of processing which resulted in reduced
material use and improved process flows.
The benefits of this
approach were as follows:
Inventory reduced from
6 months usage to
5 days worth €2.1 m
